Horsepower and torque ratings for the 2019 T1XX platform were published to GM's Fleet Order Guide Website over the weekend. However, as quickly as they were posted, on Monday morning they were gone.
The FastLaneTruck jumped on the model order guide update early Sunday morning. GM-Trucks.com then confirmed the figures were indeed listed in the guide on Sunday but before we could write this story today the numbers had been erased.
The order guide *had* listed the 2019 engines power output ratings like this:
2019 5.3L - 355hp @ 5,600rpm & 383 lb-ft of torque at 4,100rpm
2019 6.2L - 425hp @ 5,600rpm & 450 lb-ft of torque at 4,100rpm
If you're aware of the current 2018 model ratings, that's a no gain rating for the 5.3L and 5hp gain and 10 lb-ft loss for the 6.2L.
Could that be correct? Did GM let the cat out of the bag too early or were the wrong figures listed?
Another part of this puzzle is that the 2019 5.3L will carry the RPO code of L84. That's a pretty well known Chevrolet small block designation synonymous for being the most powerful Chevy small block before the LT5 and famously produced 375-horsepower.
Will we see the same for the 2019 L84 5.3L? Or will the power ratings stay the same? Either way, the engine doesn't carry the same RPO code as the 2018 model so we assume it's new in some sort of way. An exact same power rating seems unlikely but we wouldn't be surprised.
And if you're wondering the 6.2L engine will wear the RPO code L87.
Only time will tell.

Zane:
The 2.8L Duramax is an engine that will extend the capability of the Colorado and Canyon to within a stone's throw of the full-size Silverado and Sierra. From the moment you turn the key, there’s no mistaking this as a diesel engine. Noticeably louder than GM’s other gas engine offerings, owners will probably enjoy that their pickup sounds remarkably similar to the bigger 6.6L Duramax V8.
In our short drive time we were impressed by the massive amounts of low end torque for a vehicle of this size. 369 lb-ft of torque at only 2,000 rpm goes a long way. However, with only 181-horsepower, the Canyon 4x4 crew cab we drove didn’t feel as quick as its 3.6L gas-powered counterpart.
Point the nose of the GMC up a steep hill and the Duramax diesel’s benefits are immediately apparent. Nothing is going to stop this truck once it gets moving and you feel like the hand of God has your back. Acceleration is smooth and linear through the entire engine range. That’s the experience diesel truck buyers want and GM has given it to them. Bolder, louder and purposeful in nature.
Oh and did we mention fuel economy? Prepare to be impressed. We saw over 30 mpg on our drive loop. GM executive Mark Reuss confirmed to us that the final EPA number should be very close to our results. That would place the Colorado and Canyon has the most fuel efficient trucks you could buy. No wonder GM is exploring options to increase the number of Colorado and Canyon it can build. John:
What struck me first was the great look of the Canyon. Particularly from the front ¾ view. I had just left off-road testing in a 2016 Tacoma and in terms of looks, the Canyon wins hands-down. My tester was a $45,280 SLT Crew Cab with 4WD. Trucks are expensive now, but this one had it all. Premium Bose audio and Nav ($500), Spray in bedliner ($475) and Chrome assist steps ($725). I was impressed that the Canyon had Lane Departure Warning and Forward Collision Alert at no extra charge. That will cost you $500 on a Tacoma. The biggest single adder was the $3,730 Duramax engine. Although that buys a lot of gasoline, the Duramax has benefits beyond fuel economy to its fans.
Hills surrounded the venue we were attending, and they were steep. Like Zane, I was immediately impressed by how strong the Canyon I drove felt. I too noted the fuel economy. Over the past 50 miles that it had been driven in rural NY the vehicle had averaged 22.2 MPG and its peak had been 34.5 MPG (according to the truck).
Writers at this event were passing up track time in a Corvette to drive the Canyon on-road. It was one of the most popular vehicles at the event. The new Canyon and Colorado Duramax will not disappoint. GM is proud of this new truck, and as Zane’s interview with Mark Reuss proves, GM is looking hard for places to build more. The Canyon Duramax looks, drives, and acts like a winner.

The time has finally arrived. You are just weeks away from being able to buy General Motor’s 2.8L Duramax Diesel in the midsize Colorado and Canyon. Two GM-Trucks.com staffers recently had a chance to take a 2016 GMC Canyon with this engine for a spin and here’s what we thought.

Hey there, i wanna know if im able to upgrade my steering wheel from my silverado 1500 to the leather, stitched, heated wheel that you find in the LTZ / Z71 trucks.
If there is a way lemme know step by step how to do it!
thanks

A while back we sold my old sierra to get an SUV to haul the kids around in. Having a pickup is something you miss though, so recently I was looking for a fun truck to drive around and take surfing, haul household trash, etc.
I ended up getting my hands on a 1968 C20 longbed that someone gave a once-over to. The important stuff:
454 v8 with a three speed th400 auto transmission. The guy had dual purple hornies coming out right under the doors, SUPER loud and didn't smell great while driving it. I already took those off, put a flowmaster in and ran dual pipes out the sides behind the rear tires.
My question is, what now? I had a mechanic look at it and there are minor issues. I'm going to go through it and replace every wet seal, gasket, and belt but beyond that there are a couple leaks, from the valve covers and it sounds like a leak from the carb. It's got an old Rochester carb on it, I'm thinking buy a new Holley 750 and be done with it.
I'm also going to add a factory looking tach, new instrument panel bezel, and generally tighten things up.
What else should I do? It's loud and first gear has plenty of torque, but it's not fast. One reason I want the tach is I had it on the freeway and felt like I was nuzzling the redline at 60mph. Is there an easy way to improve the top end?
The bed is a layer of spray painted plywood screwed into the original wooden bed. I'd love to redo that, but the kits are pretty expensive and it looks like a lot of 50 year old bolts that would need to be blowtorched. Is it possible to shore up the original bed and spray it with a rhino liner or something?
Any other ideas?

Hello all,
2005 GMC Sierra 1500 4x4 L33 5.3 with 208k miles.
I did some research, and found that my oil pickup tube o-ring is most likely causing my oil pressure 'issues'
The 'issue' is that in the morning during the first start up of the day, the oil pressure registers low enough to trigger the low oil pressure warning. At idle in PARK it will usually stabilize (when cold) between 5 and 20 psi, but it will drop below that when idling in DRIVE as well, during the first few minutes of operation.
Asthe engine warms up, the oil pressure increases, and generally driving down the road when cold it reads 20 psi, when warm its 30-35 psi.
Like I said, I believe the culprit is the pickup tube o-ring.
My question is, what is involved in dropping the oil pan to replace this $5 part? Do I HAVE to remove the front diff and everything associated with it?
